The UE modifies DRX operation in response to identifying the conflict between the system resource and the WUS resource. A base station identifies a conflict between a system resource and a WUS resource for a UE operating based on DRX. The base station modifies a transmission to the UE in response to identifying the conflict between the system resource and the WUS resource. ## Claims ### Claim 1 A method of wireless communication at a user equipment (UE), the method comprising: identifying a conflict between a system resource and a wake-up signal (WUS) resource associated with the UE while the UE is operating based on discontinuous reception (DRX);
